Non-continuous piecewise nonlinear frequency modulation pulse with variable sub-pulse duration in a MIMO SAR radar systemThis paper proposes an implementation of non-continuous piecewise nonlinear frequency modulation (N-PNLFM) signals in MIMO radar which are composed of a sequence of N-PNLFM sub...
A non-linear frequency modulation (NLFM) waveform is in the central component of each N-PNLFM subpulse, the bandwidths of each NLFM waveforms are distributed randomly. Each subpulse can be controlled by different variable parameters in both auto-correlation and cross-correlation functions. In ...
This paper pays attention to the piecewise continuous time modeling of a hydro-turbine governing system in the process of shutdown transient. As a pioneering work, the piecewise nonlinear dynamic transfer coefficients are introduced into the system. Moreover, for different hydrograph...

First, we present a continuous time single degree of freedom PWL dynamical model of the system. Different configurations of the PWL model and their corresponding state-space regions are derived. Then, from this PWL model, extensive numerical simulations are carried out by computing time-domain ...
Many methods have been used to produce signal TFD in DRX applications, such as the Choi–Williams distribution (CWD) [16,17,18], WVD [19,20], quadrature mirror filter bank (QMFB) [21], continuous and discrete-wavelet transform (CWT/DWT) [22,23], and STFT [24,25,26,27,28] ...
